To all whom it may concern.-

Be it known that I, LIONEL M. STERN, a citizen of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Agitators, of which the following is a specification.

My invention in agitators, relates mainly to a means for stirring thecontents of a package. It has particular reference to the stirring of liquids, containing mixtures, which are subject to precipitation, due to a difference in their specific gravities.

The object of my invention is to provide a more simple and a more effective means for facilitating the stirring, mixing, or agitating of liquids, of the character referred to. than by those in vogue and previous to my invention, in so far as I am at present aware.

The features characteristic of my invention, wherein I am enabled to attain the object thereof, is depicted in the drawings hereto attached, which forms part of this specification, wherein Figure'l is a vertical, sectional elevational view of a barrel, illustrating the application of my improved agitator thereto, the same being illustrated in two difierent positions, namely, in an open position, as well as in a closed position, the former being indicated by the broken lines. Fig. 2, is an enlarged detailed view of my improved agitator, taken in side elevation, illustrating it, in the position indicated by the dotted lines of Fig. 1, together with a fragmentary sectional view, of the head and bottomof the barrel. Fig. 3, is an enlarged end elevational detailed view, taken from the left of Fig. 2, and looking toward the right thereof. Fig. 4, is a top plan view of my'improved agitator, illustrating the crank, operating handle, and bung cap, in full lines, and the shaft, and adjusting stops in broken lines. Fig. 5, is a crosssectional plan view of the upper end divided socket, shaft and bearing, therefor taken on the lines AA of Fig. 2. Fig. 6. is a similar View, illustrating the construction of the shaft, socket and adjustable stop, taken on the lines BB of Fig. 2, and Fig. 7, is a to plan view of certain parts, taken on section CO of Fig. 3'.

In these several figures, similar characters of reference are employed to indicate like parts throughout, wherein :The parts, 1, 2, 3, and 4, indicate respectively the two opposite walls, and the'head and bottom of a bar rel, embodying my invention. Secured by screws, to the bottom 4, of the barrel and concentrically situated, is a lower bearing chambered socket 5, preferably of metal, and oppositely situated thereto, and concentric ally in the head of the barrel, is the upper bearing socket, composed of the parts, 6. 7, snugly fitting a perforation in the head.

8, designates preferably a metal shaft, having a square cross-section, as illustrated in Figs. 5. 6, which has its lower extremity in bearing with the socket 5, and is secured thereto against an upward endthrust by a cotter-pin 9, as will be clear by the illustrations. The upper portion of the shaft 8, is provided with a telescopic sleeve 1A, adjustably mounted in sliding engagement with the shaft 8, but is restricted against rotation, relative thereto.

The outer surface of the telescopic sleeve 1A is cylindrical and is in bearing relation with the split socket 6. 7, the arrangement being such, that the shaft 8, is permitted to freely rotate between the lower socket 5 and upper split socket 6. 7. Cast or otherwise integrally formed with the sleeve 1A, is the bung cap 2A, provided with a laterally extended arm 3A, the arm 3A being provided with a hinged handle 4A. The handle 4A of the extended arm 3A being disposed with relation to the telescopic sleeve 1A as a crank for rotating the same, whereby the shaft 8 is A set into rotation. The shaft 8 is provided with a pair of hinged lateral arms 5A, 6A, 7A and 8A. The arms 6A and 8A are pivotally secured to the lower extremity of the shaft 8 and in proximity to the lower bearing socket 5, while the extremities of the arms 5A and 7A are pivotally secured to lugs 9A and A1, integrally formed with the sleeve 1A at its lower extremity as will be clear by the illustrations, particularly Fig. 3. The arrangement of the arms, together with the shaft 8 and the sleeve 1A, being such, as to form a central shaft and paddle, whereby upon the rotation of the shaft 8, the said arms will be adapted to swing within the barrel in a manner to stir the mixture contained therein, by the rotation of the crank handle 4A.

Fig. 2, depicts the normal position of the agitator, when in a barrel for transportation and storage, wherein it will be observed the bung cap 2A is resting upon the head of the barrel and is secured thereto, by screws, while the paddle, comprising the arms 5A, 6A, 7A and 8A is extended in the position illustrated in this figure and by the broken lines in Fig. 1. When the agitator is thus elevated, the split upper bearingsocket 6. 7 being loose will be carried with the sleeve 1A by the flange A3, out of the bung hole A2, and clear of the head 3. It then may be assembled on the sleeve 1A immediately under the flange A and while in this position inserted in the bung hole, or under the flange A4. In the former instance the agitator would be one-half extended and in the latter, it would be closed, as in the full lines of Fig. 1, while in the position Fig. 2, it is fully extended. Upon the removal of the screws and the raising of the bung cap 2A, the shaft 8, together with the arms 5A, 6A, 7A, 8A may be raised into the position of the full lines in Fig. l. The bung hole A2 being of sufficiently large bore to permit of the flanges A3, A4 of the sleeve A1 passing through. When the handle 4A is swung on its pivot into a horizontal position and the bung cap is secured. As illustrated in Fig. 2, when the handle is folded no parts will extend beyond the surface of the barrel head and therefore the parts will be protected by the upper edge of the barrel, against injury during transportation. It is obvious that the lower bearing cap 5 must be secured to the bottom of the barrel, prior to the securing of the barrel staves. When the cotter-pin 9 is once inserted, it cannot be removed without disassembling the barrel.

When the mixture contained in the barrel consists of a viscid fluid or a paint mixture having heavy pigments, such for example as white lead or con lomerate mixtures as casein or glue, it wilfbe somewhat difficult to commence the agitation of the mixture with the paddle extended in the position illustrated in Fig. 3, or by the broken lines of Fig. 1. I therefore have arranged the adjustment for the paddle, whereby the same may be more or less closed, and for this purpose I have constructed the sleeve 1A with the series of sto s A3, A4, the extreme adjustments being between the position of the bung cap 2A on the head 3, and the support of the flange A4 upon the upper split bearing socket 6. 7. Although I have shown two of these intermediate supports viz. the flanges A3, A4, I dont desire it to be understood that I am to be limited in the scope of my invention, to this particular adjustment, as a greater number of flanges may be employed as A3 ,A4 without departing from the spirit of my invention. It will be observed that in Fig. 2, the sleeve 1A is provided with longitudinal slotsA5 andA6. These are discharge outlets for any fluid which might accumulate in the sleeve and due to the adjustment of the shaft 8 in the said sleeve, the fluid would be impelled by the end of the shaft in the manner of a piston, within the sleeve, which would interfere with the action of the sleeve 1A on the shaft 8 and to relieve the resistance which would be thus set up, upon the liquid, I provide the vents A5 and A6, which are longitudinai recesses penetrating through the walls of the sleeve A1, whereb v upon the plunging of the shaft 8 within, the sleeve the fluid therein, would be driven out of the openings A5 and A6 as the end of the shaft, acting as a piston on the fluid would be moving upwardly, with respect to the sleeve. It is obvious that the bung cap 2A, when screwed down upon the barrel head 3 in most instances, would effect a sufficiently tight connection between the metal. and wood to prevent leaking, but in mixtures where the fluids are somewhat volatile, such as rubber paints, containing naphtha and other water proof paints, a sufficiently tight joint can be made by introducing a gasket between the head 3 and the bung cap 2A, such as a rubber ring or other well-known packing. In considering the construction of these agitators and their arrangement in packages, such as the barrel illustrated, I have considered the device as a whole and have so constructed the barrel, containing the agitator, in a manner whereby the two are made inseparable. The lower bearing cap, which is secured to the bottom 4, carries the shaft by a cotter-pin which prevents the removal of the agitator from the barrel and thus the combined agitator and barrel, is employed in lieu of the usual barrel, without agitators, and is designed as a substitute therefor.

I am aware that prior to my invention, extensible paddles have been in vogue for agitating cream, thick or viscid substances, and the like, and I do not claim a device of this character broadly as my invention. The features of the invention, lie more particularly in the construction of the package and contained agitator located between and con nected with the two diametrically opposite walls of the package and the means for varying the lateral extensions of the agitator by a novel method of adjustment and further in the sealing of the package with an exterior portion of the apparatus, and

Having full) described my invention I claim as new and desire to secure by Letters Patent of the U. S.
